For a retro pin-up calendar project called “Milky PinUps,” photographer Jaroslav Wieczorkiewicz of AurumLight Studio in London shot high speed photos of models “wearing” only milk. These “liquid illustrations” were inspired by the vintage pin-up illustrations from the 40s and 50s of artists Gil Elvgren, Alberto Vargas, and others from that era. If you’re interested in learning how it’s done by Wieczorkiewicz himself, he’s offering Milk Workshops in Australia and Switzerland until the end of 2013. You can see more images from the series at his blog.
